In the first part of the report of the GTZ expert group an overview on the basics of integration and tax harmonisation within a common market is given. Chapter II. concentrates on the problems of national and international tax law regarding double taxation before the harmonisation process within the EU is described in detail. This process is not a best practice example but at least the experiences made in the course of the last five decades are interesting enough and might contribute important information for regions, which more or less recently have started a similar endeavour. The harmonisation needs are discussed for value added taxation (VAT), excise taxation, and income taxation. The problems of tax administrations, procedures laws, taxpayers’ rights and obligations as well as tax compliance are also taken into consideration. The second part of the study reviews the national tax systems within the EAC member countries. Before the single taxes are described in more detail, the macroeconomic situation is illuminated by some basic figures and the current stand of the inner-community integration analysed. Then the single tax bases and tax rates are confronted to shed some light on the necessities for the development of a common market within the near future. Again the value added tax laws, excise taxes and income taxes are discussed in detail, while regarding the latter the focus is on company taxation. For a better systematic analysis the national tax laws are confronted within an overview. The chapter is closed with a summary of the tax rates applied and a rough estimation of the tax burdens within the Partner States. The third part of this report contains the policy recommendations of the expert group following the same structures as the chapters before and presenting the results for the VAT, the excises and the corporate income tax (CIT). Additionally the requirements for tax procedures and administration as well as problems of transparency and information exchange are discussed in detail before the strategic recommendations are derived in close relation to the experiences made within the EU harmonisation process. The recommendations are based on the following normative arguments: (1) Tax harmonisation is a basic requirement for economic integration. (2) Equality of taxation is an imperative of tax justice and demands the avoidance of double taxation as well as the combat of tax evasion and corruption. (3) The avoidance of harmful tax competition between the Partner States. (4) The strengthening of taxpayers’ rights in tax procedures. Hence, all kinds of income, goods and services should be taxed once and only once.

The paper sheds some light on the education returns in Germany in the post war period. After describing higher education in Germany the current stand of higher education financing within the single states is presented. In six states tuition fees will be introduced in 2007/08 and discussions are going on in even some more. In the second part of the paper an empirical analysis is done using longitudinal data from the German social pension system. The analysis over the whole lifecycle renders results which proof that the higher education advantages are quite remarkable and might be a justification for more intensified financing by tuition fees. But all this has to be embedded into an encompassing strategy of tax and social policy, especially to prevent a strengthened process of social selection, which would be counterproductive for an increased and highly qualified human capital in Germany.

This paper gives a review on the theoretical foundation for fiscal decentralisation and a status quo analysis of the intergovernmental relations in Mongolia. It consists of two parts. Part I briefly reviews the theories of fiscal decentralisation and its impact on the nations’ welfare considering the major challenges for a transition economy. Part II of the paper describes the general structure and scope of the government and examines the current fiscal autonomy in Mongolia focusing on the four main areas of intergovernmental relations. This paper concludes that local governments in Mongolia are still far away from having the political, administrative and fiscal autonomy. New approaches for the assignments of expenditures and revenues in Mongolia are urgently needed.

The paper describes the exchange program in between the University of Wisconsin/ Milwaukee and the University of Potsdam in the field of economics. It discusses in detail the development of the program, including the problems and challenges. Additionally a brief description of the curriculum is presented. Then the future possibilities of the Transatlantic Degree Program (TDP) are discussed and the influences and problems of the Bologna process analysed.

Many European countries have experienced a significant increase of unemployment in recent years. This paper reviews several theoretical models that try to explain this phenomenon. Predominantly, these models claim a link between the poor performance of European labor markets and the high level of market regulation. Commonly referred to as the Eurosclerosis debate, prominent approaches consider insider-outsider relationships, search-models, and the influence of hiring and firing costs on equilibrium employment. The paper presents empirical evidence of each model and studies the relevance of the identified rigidities as a determinant of high unemployment in Europe. Furthermore, a case study analyzes the unemployment problem in Germany and critically discusses new reform efforts. In particular this section analyzes whether the recently enacted Hartz reforms can induce higher employment.

Revisiting public investment
(2004)
The consumption equivalence method is the theoretical basis of public cost-benefit analysis. Consumption equivalence public capital prices are explicitly introduces in order to sufficiently care for the opportunity cost of public expenditure. This can solve the dispute about the social rate of discount within public cost-benefit analysis witch was generated on a criterion looking similar to the capital value formula, known as Lind’s approach. The social rate of discount is liberated from opportunity costs considerations and the discounting away of the effects for future welfare vanishes. The corresponding question whether one should accept a positive value of the pure rate of social time preference is an old issue. Its current state between the prescriptive and descriptive view can also be interpreted as a consequence of the oversimplification of standard cost– benefit analysis. But apart from an economic self-process the pure rate of social time preference is also defined as a business-as-usual value of social distance discounting. Hence, a political choice has to be made about this rate which is free in principal.

An exhaustive and disjoint decomposition of social choice situations is derived in a general set theoretical framework using the new tools of the Lifted Pareto relation on the power set of social states representing a pre-choice comparison of choice option sets. The main result is the classification of social choice situations which include three types of social choice problems. First, we usually observe the common incompleteness of the Pareto relation. Second, a kind of non-compactness problem of a choice set of social states can be generated. Finally, both can be combined. The first problem root can be regarded as natural everyday dilemma of social choice theory whereas the second may probably be much more due to modeling technique implications. The distinction is enabled at a very general set theoretical level. Hence, the derived classification of social choice situations is applicable on almost every relevant economic model.
